9 Claims.

My invention relates to a machine for delivering hot, ironed material in a laundry to a position in which the material may be neatly folded.

An important object of the invention is to provide means in such a machine whereby the hot, ironed material may be cooled prior to the time that it is folded by the operator. Heretofore operators have frequently burned their fingers when attempting to fold hot, ironed material as soon as it comes out of the ironing means.

Another object of the invention is to provide improvements with relation to such a machine that will be superior in point of positiveness in operation and convenience in use, together with relative simplicity in construction, and general efficiency.

The invention also comprises novel details of construction and novel combinations and arrangements of parts, which will more fully appear in the course of the following description. However, the drawings merely show and the following description merely describes an embodiment of the present invention, which is given by way of illustration or example only.

' In the drawings, like reference characters designate similar parts in the several views.

Referring more in detail to the drawings, a reference numeral designates an endless belt of an ironing means. Washed laundry is ironed between oppositely disposed endless belts 5 and 6. A roller 1 is shown for driving the belt 5, while the belt 6 operates on an idler roller 8. The belts 5 and 6 are driven in the directions of the arrows in Figure 2. Suitable bearings 9 and I0 support shaft l2, upon which the roller 1 is mounted. Part of the frame of the ironer is shown at I3. A guide l4 directs ironed material l5 that is discharged from the ironen, Thus far is conventional construction, so further detailed drawings and description of same are deemed unnecessary for those skilled in the art.

The present delivery machine is mounted on a frame supported by wheels l8, so that it may be moved from place to place. In the drawings, the present machine is shown fastened to the frame |3 of the ironer by means of straps l9.

An endless belt extends around driven roller. 2| and idler 22. The belt 20 may be a series of belts or webbing placed side by side, as shown in Figure 1. A plate 23 isbolted on the frame IT by means of screws 24 and supports the upper stretch of the belt or webbing.

The driven roller 2| has a shaft 25 upon which is mounted a ratchet gear 26. The ratchet gear. 26 and. its actuating means, hereinafter to be described, are enclosed in a safety housing 21. A hearing 28 is provided on the frame I! for the shaft 25. I 7

Two pawls 29 and 30' are arranged for their respective teeth 3| and 32 to engage the teeth of the ratchet gear 26. Springs 33 and 34 respectively tend to draw the pawls 29 and 38 into engagement withthe ratchet gear 25. The outerv ends of the springs 33 and 34 are relatively fixed upon the frame I! by means of bolts 35 and 36.

Control means for thepawls comprises a sliding bar 31 that has at oneend an elongated eye 38 slidably on the bolt 36. The opposite end of the bar31 has a series of sockets 39, 4|) and 4| to provide different a'djustments for the bar 31. A bracket 42 carries a pin 43 with'which the sockets 39 4B or 4| may selectively engage. Y

An adjusting lever 44 is pivotally connected with the sliding bar 31 at 45 and provided with a relatively fixed pivot 46 upon the frame of the machine. The upper end of the control lever'44 has a handle '41 for manipulation of the lever.

Operating means for the pawls 29' and 30 in cludes a rocker plate 48 that oscillates about the spindle 49. Rocking motion is imparted to the plate 48 by means of a connecting rod 53 that is adjustably fastened to the plate 48 by means of an eye 5|. A set screw 52 fastens the rod in the desired position in the eye 5|. A single bolt 53' fastens the eye 5| to the plate 48 and pivotally fastens the lower end of the pawl 29 to the plate 48. A bolt 54 pivotally fastens the lower end of the pawl 30 to the plate 48.

The upper end of the connecting rod 50 iseccentrically connected with the drive roller 1, as shown at 55. A wheel 56 on the shaft of the roller 1 is the means that is directly eccentrically connected with the connecting rod 50.

Offset brackets 51 and 58 are mounted on the sliding bar 31. A bolt 59 spans the space between the bracket 51 and the bar 31, while a bolt 68 spans the space between the bracket 58 and the bar 31. The bolts 59 and 60 are laterally spaced in order that the bolt 60 may keep the pawl 30 out of engagement with the ratchet wheel 26 in two positions of the bar 31.

In the operation of the machine, hot, ironed material is fed from the belt 5 of the ironer, down the guide l4 and on to the belt means i=6. The belt 20 travels a sufiiciently long distance and sufiiciently slow to cool the material enough in order that it may be folded by'an operatorias the material comes ofi of the belt 20 at the end 62, without burning the operators fingers.

The actuating means for the belt 20 may .be disconnected from the driving means by moving the hand lever 44 to the broken line position 6'3. When the lever is .in the latter position, the socket 39 is in engagement with-the bolt 43 and the pins59 and 60 withdraw thepaw'ls Q29 and 3.0 from engagement with the ratchet wheel 26.

When it is desired to operate 'the'be'lt or webbing 21] at Ya slow rate of speed, the lever 4'4 is moved to the full line position of 'Figure 2. In this position the single pawl 29 is permitted to engage and actuate the ratchet 'wheel 26, in the direction of the arrow AinlEigure 5. When the lever-His in .the full "lineposition, the socket 453 is-engaged by the pin 43.

When .it .is desired to operate the delivery .machine at its fastest speed, the hand lever 44 is moved to the broken line position 64. This permits the pawls 29 and 3D to alternatingly engage the ratchet wheel 26, [since the springs 33 and 3'4 .tend at all times to .draw the pawls into engagement with the ratchet wheel. The action of these springs is only restrained .by the pins 59 and 58. 'However, in the high speed position, neither of these p nsmaintains its respective pawl away from the ratchet wheel.

"The actuating means .Tor the .pawls comprises the rocker plate 48 whichis rocked by means .of the connecting rod 5. 3,, which in turn is driven by .the .eccentric .55 connected with the roller 1.

The .plate Adis-rockedat a uniform speed with respect .to the speed of-Qperationof the roller 1, but the .presentdelivery machine is operable at diiTerent speeds relative to the speed "of operation'of the-roller 1.. However the speedoi operation of the delivery .machine is necessarily at a'determinable ratio -with respect to the speed of operation of roller 1 of the ironing machine driving the ironer !belt *5, since the connecting rod :50 operatively connects the ironer with the delivery machine and since the-delivery machine isdependent upon :the operation of the ironing machine. However, this ratio :is :subject to change, -of course, :so that the highest speed of the delivery belt .20 .may be equal to, or below, that er tllBrlfOIIBIbGlt *5. It is important that the "slow speed of thedelivery belt 2% be'substantially below that- 0f the ironer belt 5.

While I have illustrated and described what I now regard as :the preferred embodiment of my invention, the construction is, of course, subject to modifications without :departing from the spirit and scope of my invention. I, therefore, do not wish to restrict myself to the particular form of construction illustrated and described,

;iacent to the delivery means for controlling said reduction mechanism to desirably regulate the speed of the delivery means.
